Triangles ABCD of side AB are larger than side BC by 1 centimeters and less than side AC by 1 cm Find the perimeter of triangle ABC if it is known that A C is 6 cm.
By condition, the AB side is one centimeter smaller than the AC side, which is 6 cm.
AB = AC – 1 = 6 – 1 = 5 cm.
By condition, the AB side is 1 cm larger than the BC side, then the BC side is 1 cm less than the AB side.
BC = AB – 1 = 5 – 1 = 4 cm.
Then the perimeter of the triangle ABC is equal to: Ravs = AB + BC + AC = 5 + 4 + 6 = 15 cm.
Answer: The perimeter of triangle ABC is 15 cm.
